Plate movement is thought to be driven by a combination of the motion of the seafloor away from the spreading ridge (due to variations in topography and density of the crust, which result in differences in gravitational forces) and drag, with downward suction, at the subduction zones.

It divides into two strands on unwinding and forms replication fork just like DNA does.And the same unwinded strands can be incorporated into the daughter DNA molecules and thus becomes semiconservative in nature.Source(s): .ating Newest Oldest.

DNA replication is the process by which DNA makes a copy of itself during cell division. 1  The first step in DNA replication is to âunzipâ the double helix structure of the DNA molecule. The separation of the two single strands of DNA creates a âYâ shape called a replication âforkâ. 2  The two separated strands will act as templates for making the new strands of DNA. 3  One of the strands is oriented in the 3â to 5â direction (towards the replication fork), this is the leading strand.
